Restorative & Materials · single question
An elderly patient with a full-time caregiver needs Class V restorations. Which material is MOST appropriate?
Show answer and explanation
Correct answer: A. Glass ionomer cement
Glass ionomer cement (GIC) is ideal for elderly high-caries-risk patients: fluoride-releasing (cariostatic), chemically adhesive to tooth structure, moisture-tolerant, technique-insensitive. Source confirms: 'Glass ionomer (puse esta).'
- A. CORRECT. GIC — fluoride-releasing, moisture-tolerant, chemically adhesive. Ideal for elderly high-risk patients.
- B. SDF arrests caries but stains lesions black and is not a restorative material — doesn't restore function.
- C. Amalgam requires significant tooth preparation and has no fluoride release — less appropriate than GIC for Class V.
- D. Composite resin requires excellent moisture control and bonding — challenging in elderly patients with compromised cooperation.
